Access vs diversity in bookshops

I recently visited two of my favorite bookshops in New York, St Marks and the Shakespeare & Co on Broadway. Both shops used to have great philosophy sections. However, they have adopted the approach of presenting larger format books, and turning many of the books face-out, and consequently they now they carry a far smaller selection, barely anything beyond the top-of-the-pops. They've eliminated the one reason why I love going to bookshops: when you search for a specific title, you often find lesser-known works shelved nearby. Now, rather than a dozen books on or by a particular topic or author, the shelf only displays two or three. The bookshops appear to have ceded diversity to the Internet, and focused instead of appearing easy to access. It is a massive loss for readers.
